Systems and methods for communication with RFID tags
First Claim
1. A method of bridging communications with a radio frequency identification (RFID) tag, comprising:
- providing a RFID tag configured to receive first band RF signal communications and to transmit second band RF signal communications;
providing a communication bridging device configured to receive third band RF signal communications and to transmit first band RF signal communications;
receiving third band RF signal communications at the communication bridging device from a tag interface device, processing the received third band RF signal communications on the communication bridging device to obtain data from the received third band RF signal communications, and re-transmitting the obtained data in first band RF signal communications from the communication bridging device to the RFID tag; and
receiving the first band RF signal communications at the RFID tag from the communication bridging device, processing the received first band RF signal communications on the RFID tag, and transmitting second band RF signal communications from the RFID tag;
wherein the first band is a multiple channel-based frequency band;
wherein the second band is a non-channel based frequency band;
wherein the third band is a frequency band that is different from the first and second bands; and
wherein the RFID tag is configured to remain associated with an object as the object moves from one geographic location to another geographic location.

Abstract
Communication between a multi-band RFID tag device that communicates on first and second bands with other devices may be enabled, using a bidirectional communication bridging device that converts first band signals of the RFID tag device to third band signals of another device, and vice-versa. Examples of third band-capable devices that may be bridged for communication with the first band of a RFID tag device include WiFi devices such as smart phone, notebook computer, WLAN router or any other type of WiFi enabled device. In one example, a tag interface control device may be provided in the form of a WiFi-enabled handheld unit that communicates with a multi-band RFID tag through a bridging device using NBFM radio frequency (RF) communications to retrieve or change stored data and/or change the tag operation. Such a WiFi-enabled handheld unit may be configured to be relatively small, portable, and/or battery or wireless-powered.
